  • Does X-CAP2 fit to the thread of my lens?

    X-CAP2 is designed for compact system cameras and is available in some popular filter sizes. Please use a step-up/down adapter ring on other filter sizes of lens.

  • Does X-CAP2 cause vignetting on my lens?

    We don’t know either, because we don’t own the lens.
    We provide a Papercraft of X-CAP2. Before buying the X-CAP2, you could download and make a papercraft to test vignetting on your own lenses.

  • Does X-CAP2 be used with an additional UV protection filter?

    X-CAP2 could be used on a filter with the same size. Due to the increment of thickness of the filter, vignetting is possibly caused on a wide angle lens.
